BURN

Burn - damage to body tissues caused by the action of heat or the action of certain chemicals There are four degrees of burns: 1.redness of the skin, 2.blistering, 3.necrosis of the entire thickness of the skin, 4.charring of tissue.

The severity of a burn is determined by the size and depth of tissue damage. The larger and deeper area of tissue damage, the more difficult for a burn injury. First aid for burns is to eliminate the influence of external factors and treatment of wounds.

The first degree. Affected the upper layer of squamous epithelium. Appears reddening of the skin, slight swelling and pain. After 2-4 days recovery occurs. The victim was exfoliated epithelium, traces of destruction remains. Second degree. Keratinizing epithelium is damaged to the growth layer. Forming small blisters with serous contents. Fully healed by regeneration from surviving the growth layer for 1-2 weeks The third degree. Affects all layers of the epidermis and dermis.

first-aid Plays an important role to provide self-help and mutual aid. Its main purpose is to stop the action of striking a factor on the victim. For example, in thermal contact burns to remove the victim from the source of the burn and to cool the skin surface (under cool running water for at least 15 - 20 minutes (only if not the integrity of the skin); actually no later than 2 hours after of burns), and electric shock - contact with the source to interrupt the current in chemical burns - rinse or neutralize the active ingredient At this point you can not use oily creams and other fatty foods. A very common misconception that burning need to lubricate something bold - for example, sour cream or vegetable oil. Such unacceptable, such an action will only aggravate the severity of lesions, and staff at the hospital have to remove the oil film, causing additional suffering to the patient. It is not recommended to remove yourself from the victim's burnt fragments of clothing: this manipulation can lead to detachment of large areas of skin, bleeding, and subsequently to the wound infection
